Process Evaluation and Impact Results of the Worksite Component of a Multilevel, Multicomponent Obesity Prevention Trial in Six Native American Communities

Native Americans (NA) have higher obesity rates compared to other populations. Employed adults spend a significant amount of time at work. OPREVENT2, an obesity prevention trial in 6 NA communities, included a worksite component that incorporated nutrition and physical activity educational media, competitions, tastes tests, and coffee station makeovers. Process evaluation results indicate a well-implemented worksite component based on team standards. Statistically significant improvements of coffee stations healthy offerings (p = .006), but none in health policies and resources, were observed. Partnering with businesses to create healthier working environments was successful and future trials should investigate the effects on an individual level.
